Flowmaster 50 Series Delta Flow Mufflers Reviews

I bought this over the 40 series because I wanted something that could be driven without being annoying, but still had a rumble to it. And this is perfect. At idle it sounds like a boot and is nice and low. From 1000-2000 rpm its super quiet on the inside, which is what i wanted. But when revved, she sounds MEAN. Great muffler here
